Wind Alarm App for Sailors
Monitor a supported station near your harbour or sailing club. Use WindUp alongside your marine forecast when planning a sail.
Choose conditions for your equipment and experience. A station reading does not establish that a session is safe.
What WindUp does for sailors.
- Check station observations before leaving the dock
- Choose conditions for your boat and planned session
- Compare the current wind with your marine forecast
WindUp is a free live wind alarm — monitor a supported station for your chosen conditions. On iOS, allow Critical Alerts to sound through Silent or Focus. Delivery depends on your device and connection.
What wind speed do you need for sailing?
The useful wind range depends on the boat, sail plan, crew and water conditions. The 8–20 kt example shown here is an alarm-window illustration, not a recommendation for every boat. Use your boat’s guidance and local forecast to plan.
Gusts, not just averages
Review gusts alongside the average, sea state and forecast trend. Reefing decisions depend on the boat and crew; a station alert cannot decide the sail plan for you.
How to set your sailing alarm
Choose a supported station with useful exposure for your spot. Set conditions based on your equipment, experience and local guidance. Check the timestamp and conditions on arrival; a matching station reading is not a safety assessment.
Reading the wind for sailing
A shore station measures wind at its sensor. Your boat’s apparent wind also depends on boat speed and heading. Check how exposed the station is before comparing it with conditions on open water.
